Answer:
x = 3 [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
Given
[tex]\frac{5+x}{x}[/tex] = [tex]\frac{15}{6}[/tex] = [tex]\frac{5}{2}[/tex] ( cross- multiply )
5x = 2(5 + x) ← distribute
5x = 10 + 2x ( subtract 2x from both sides )
3x = 10 ( divide both sides by 3 )
x = [tex]\frac{10}{3}[/tex] = 3 [tex]\frac{1}{3}[/tex]

Find the percent of markup for $40 marked up to $59.75. Round to the nearest percent.
Answers
Answer:
49%
Step-by-step explanation:
Markup is the difference between the selling price and the cost divided by the cost times 100%
Cost = 40
Selling = 59.75
% = (59.75 - 40)/40 * 100%
% = (19.75 / 40) * 100%
% = 49%

3{4-2(3+4)} solve and show your work
Answers
Answer:
Step-by-step explanation:
You could start by using pemdas which start with parentheses so since 3+4 is in parentheses add those first and you'll get 7 then solve the remaining 4-2 in the bracket so 4-2 is 2. Since there is no plus sign you multiply 7 by 2 then multiply by three so 7x2 is 14 then 14x3 is 42 so your answer Is 42

Maria collected some stones at the beach. Now she wants to make a clear plastic container to display the stones. To plan the container, Maria decides that she must first find the volume of the stones. Maria had an aquarium that is shaped like a rectangular parish. It's 8 inches wide, 16 inches long and 10 inches high. Maria pours some water onto the aquarium. She finds that the water reaches to the height of 4 inches. Find the volume of the water in the aquarium. Next, Maria now puts the stones on the aquarium. She measures and finds that the water reaches to new height of 7 inches. Find the volume of the stones
Answers
Answer:
The volume of the stones is 382 cube inches.
Step-by-step explanation:
The dimensions of the aquarium are;
length = 16 inches
width = 8 inches
height = 10 inches
The height of the water in the aquarium = 4 inches
i. Volume of the water in the aquarium = length x width x height
= 16 x 8 x 4
= 512 cube inches
The volume of water in the aquarium is 512 cube inches.
ii. The new height of water = 7 inches.
New volume of water = 16 x 8 x 7
= 896 cube inches
The new volume of water is 869 cube inches.
The volume of the stones = New volume of water - initial volume of water
= 869 - 512
= 384 cube inches
The volume of the stones is 382 cube inches.

the equation 3x square -12x+(n-5)=0 has equal roots find the value of n
Answers
Answer:
n = 17
Step-by-step explanation:
For a quadratic equation to have equal roots b²-4ac should be equal to zero in the quadratic equation ax²+bx+c=0.
Equation : 3x² - 12 x + ( n - 5) = 0
a = 3, b = -12, c = ( n - 5)
b² - 4ac = 0
(-12)² - (4 x 3 x (n - 5)) = 0
144 - 12( n - 5 ) = 0
12( n - 5 ) = 144
n - 5 = 12
n = 17
Check if it's true :
3x² - 12 x + ( 17 - 5) = 0
3x² - 12 x + 12 = 0
3(x² - 4x + 4) = 0
(x² - 4x + 4) = 0
(x - 2)(x - 2) = 0
x = 2 , 2

A line has a slope of -8 and includes the points (-10, 0) and (-9, z). What is the value of Z?
Answers
Answer:
Step-by-step explanation:
Let L be the given line, then, with a slope of -8
L : y = -8x + b
where b is to be determined from the included point A(-10,0).
Substitute point A in L to get
0 = -8 (-10) + b
solve to get
b = -80
therefore
L : y = -8x -80
Now substitute B(-9,z) in L
z = -8(-9) - 80 = -8

Answers
Answer:
119 or 118.726577
Step-by-step explanation:
We should use the Pythagorean Theorem to solve this problem.
a^2+ b^2=c^2
64^2+100^2=c^2
4096+10000=14096
c^2=14096
c=\sqrt{14096}14096
And the root of 14096 is 118.726577.
So the Answer is About 119 meters, or 118.726577

Answers
Answer:
The large square covers more
Step-by-step explanation:
Given
See attachment for squares
Required
Which covers more plane
The large square has the highest dimension and by extension, it has the highest area.
This means that, less large squares will be needed to cover more areas compared to other sizes of the squares.
Take for instance, the following analysis;
Large square
Dimension: 3 by 3;
[tex]Area=3*3 = 9[/tex]
Medium Square
Dimension: 2 by 2
[tex]Area = 2 * 2 = 4[/tex]
Small square
Dimension: 1 by 1
[tex]Area = 1 * 1 = 1[/tex]
The square with the largest area covers more of the plane.
Hence, the large square covers more of the plane
